The Eemann Tech ACE XR trigger system is a purpose-built competition upgrade for 2011 and 1911 platforms. A roller-bearing pivot mechanism eliminates lateral wobble, delivering a straight, consistent pull with a tactile reset designed for fast split times. Paired with Eemann Tech's matched sear and disconnector geometry, the ACE XR is a top choice for Open and Limited shooters chasing sub-3-pound DA/SA and single-action setups.
